Geology
[edit]The Intrusive Suite of Merced Peak dates to roughly 98 Ma.[1] The formation dates to mid-Cretaceous. It lies within the volcanogenic Minarets sequence, and comprises the granodiorite of Jackass Lakes and the leucogranites of Timber Knob and Norris Creek. Most of the suite is the former.[2]
